MONTVALE, NJ – Making its showroom debut in August will be the new Mercedes-Benz 2013 G63 AMG, featuring a state-of-the-art powertrain, new design, and improved efficiency.

Fuel consumption has been reduced by 13 percent (European cycle) thanks to the biturbo eight-cylinder engine, along with the AMG SPEEDSHIFT PLUS 7-speed automatic transmission, the alternator management system, and the ECO stop/start function. The seven-speed automatic gearbox features three drive modes and an automatic rev-matching function for downshifting, creating an incredible range of versatility. In “Controlled Efficiency” mode, the ECO stop/start function is active, shutting down the eight-cylinder engine when the vehicle is stationary. “C” mode is also characterized by smooth accelerator and transmission characteristics and early gear changes; the vehicle is usually started in second gear in this mode. The AMG instrument cluster includes a green “ECO” symbol, indicating when the ECO stop/start function is on.

The AMG 5.5L V-8 biturbo engine develops a maximum output of 544 hp and a torque of 560 lb-ft., enabling the 2013 G63 AMG to accelerate from zero to 60 mph in just 5.3 seconds, with a top speed of 130 mph (electronically limited), according to the automaker.

In the Sport (S) and Manual (M) modes, the ECO stop/start function is off, and the engine and transmission behave more aggressively. Short, precisely defined ignition and injection retardations mean shorter shift times under full load. The efficiency of the AMG SPEEDSHIFT PLUS 7-speed automatic transmission system is further enhanced with a new torque converter with centrifugal pendulum, friction-reducing bearing and transmission oil thermal management.

The suspension/damper settings in the AMG Sports chassis have been adjusted for the more dynamic handling characteristics of the new model. To reduce vibration and noise, the design engineers at Mercedes-AMG also implemented a wide range of measures including optimized bearings for the automatic gearbox, transfer case, and engine cut vibration and noise levels.

The 2013 G63 AMG runs on new AMG split 5-spoke light alloy wheels as standard equipment. The 9.5 × 20 titanium-grey-painted wheels with high-sheen finish are fitted with 275/50 R 20 tires. Ventilated all-around, perforated brake discs with dimensions of 14.8 × 1.42 inches at the front and 13 × 0.79 inches at the rear provide optimum thermal capability and deceleration, according to the automaker. The front axle is fitted with a six-piston fixed-caliper brake system taken from the ML 63 AMG, with a single-piston floating-caliper system on the rear axle. Standard red painted calipers are a special highlight of the G63 AMG.
